COMMODE-PAN STRUCTURE FOR. TILTING BEDS.

Specification of Letters Patent.

Patented Feb. 10, 1914.

Application filed February 12, 1912. Serial No. 677,166.

To all whom it may concern Be it known that I, HENRY E. BOWN, a citizenof the United States, residing at Columbus, in the county of Franklinand State of Ohio, have invented certain new and useful Improvements inCommode-Pan Structure for Tilting Beds, of which the following is aspecification.

My invention relates to commode pan structure for tilting beds and isparticularly designed as an improvement in apparatus for application tobeds designed to be utilized in surgical operations and for othersimilar objects.

It is aimed, in portion, to provide a structure of commode pan which isapplicable to surgical beds and which may be gradually adjusted tomaintain a substantially horizontal position during the gradual tiltingoperation of the bed.

It is designed to be detachable and preferably comprises a seatpivotally secured at one end and having its other end capable ofadjustment in an arcuate direction. In the efi'ectuation of suchadjustment, I desirably utilize a base having a ratchet and yokestructure, the yoke being secured to the free end of the seat and beingpivotally mounted thereon, so as to permit of assuming various bracingrelations to the seat and the base. In conjunction with the seat andbase structure, I utilize a pan proper which is readily removable andthe removability of such pan renders it possible to collapse the seatstructure so that it occupies a minimum space only and greatlyfacilitates the insertion of the same beneath the patient upon the bed.In conjunction with this commode pan structure, I desirably use anadjustable back rest, which may be adjusted so as to maintain thepatient in a sitting posture.

One of the essential and advantageous features of my seat structure,resulting partially from the removability of the pan from beneath theseat while in comparatively elevated position, is the fact that the saidstructure serves to maintain the body of the patient in a position forready cleansing and treatment or further operation. The operations towhich this device is peculiarly adapted, are any of those operationswhich are necessary in the vicinity of the rectum.

The preferred embodiment of my invention is shown in the accompanyingdrawings, in which similar characters of reference designatecorresponding parts, and in which- Flgure 1 is a perspective view of atilting bed structure with my invention applied thereto, Fig. 2 is adetail view in elevation of the pan structure in operative position,and, Fig. 3 is an end elevation of the structure shown in Fig. 2.

In the drawings, the ordinary bedstead is shown at l and centrally andpivotally mounted thereon is what may be termed the bed proper 2 havinga mattress 3 thereon and being elevated by means of a worm and rackstructure 4 controlled by the crank handle 5. The racks are shown at 6as being pivotally secured as at 7 t0 the bed proper and extendingthrough casings supported by hangers 8 carried upon the bedstead 1. Theyare under the control of worms mounted upon shaft 9 which is rotatableas aforesaid, by the crank handle 5.

The tilting bed proper is desirably fitted with a back-rest 10 pivotallymounted at one end upon the base 11 having ratchet notches 12 thereinfor the adjustable reception of a bracing yoke 18.

The bed pan structure comprises a seat- 14. pivotally secured to arectangular base 15 having ratchet notches 16 formed therein and theseat is adjustable and maintained in adjusted position by the coactionof a yoke member 17 with such ratchet notches 16, the notches withinwhich said yoke rests, determining the angle of the seat to its basewhich desirably rests flat upon the mattress of the bed proper, if amattress be used. The seat is desirably provided near its pivoted endwith chains 18 and hooks 19, whereby the commode pan structure may bereadily attached to the bed proper.

The seat is apertured as at 20 and beneath the aperture there areprovided slideways 21 for the reception of flanges 22 upon the commodepan 23, which is provided with a handle 24:. This commode pan may,therefore, be removed or inserted at will.

In operation, assuming that the patient is lying at full length upon thebed, the commode pan structure with the pan removed, and in collapsedposition, is slid beneath the patient and as the crank handle 5 isrotated to tilt the bed, the seat is gradually swung upon its pivot tomaintain a substantially horizontal position. Thus the patient may becaused to assume a sitting posture by degrees and such sitting posturemay be com plete or partial. When the seat is in proper position, thepan is slid into place if it is desired to utilize the pan or thetilting bed may be returned to normal position, leaving the patient in aposition suitable for operation in a well known manner. If the pan isused as it may be, for the collection of poisonous matter or for thedrainage of a wound or any other similar purpose, it may then be removedand the bed lowered: to normal position, whereupon the limbs of thepatient are maintained in a position to tacilitate cleansing of thewound.

it will be seen that I have provided a structure of commode pan, whichis readily attachable to a bed and may be adjusted to vary its anglewith relation to the surface of such bed. It is par icularlyadvantageous to utilize a tilting bed structure since the movement ofthe head of the bed proper upwardly, tends to more the patient toward asitting posture, while the adjustment of the seat of the commode panstructure causes it to maintain a horizontal position while constantlychanging its angle with relation to the tilted bed. In this manner thepatient may be readily caused to assume a sitting posture and ashitherto pointed out, the seat and base may be inserted beneath thepatient with small difiioulty, because of its capability of collapsingto occupy aminimum space.

What I claim, is

l. A commode pan support for tilting beds comprising a seat capable ofarcuate adjustment from a normally flat position, means for securing apan to said seat.

2. A commode pan support for tilting beds comprising a seat capable ofadjustment from a normally flat position to compensate for the tiltingof the bed, and slideways on said seat for supporting a pan.

3. A commode pan support for tilting beds comprising a seat capable ofadjustment from a normally flat position to compensate for tilting, andmeans for attaching said seat to the side of the bed.

A commode pan support for tilting beds comprising a seat pivoted-at oneend, means for varying the elevation of the opposite end, chainsfastened at. one end to said seat, and hooks on the other end forengaging the side of the bed at any point.

A commode pan support for tilting beds comprising an adjustable seat,and a removable pan secured to said seat.

in testimony whereof I aiiix my signature in presence or two witnesses.
